Today on Monday Mysteries we have a special mystery courtesy of Chris: a mystery shadow dancer.

Chris offers the following animated sequence of these still images for your consideration [note: depending on your browner you may need to click on the photo to open it in a new window to see the animation]:

Shadow Dancer

What the heck is that “dancer” doing, eh? Well, here’s a slowed-down version of the sequence:

Shadow Dancer – Slower

Still puzzled? I know I was — even when he told me that I was the “dancer” in the photo! The only thing I knew that I did when he was taking photos was take a photo of a hilly scene [click on the photo below and then click on the version that opens to get the full size of this image]:

What the Shadow Dancer is Seeing

Yup. The “Shadow Dancer” is waving a cell phone back and forth to get a panorama of the scene before her. Never would have believed it, but that’s what it looks like when a shadow does it.

So there you have it. One of the very few Monday Mysteries that gets solved in the same post.

Enjoy.
